APPARATUS FOR DISPERSING LIQUIDS OR MAKING SPRAY.

SPECIFICATION forming part of Letters Patent No. 709,556, datedSeptember 23, 1902. Application led .Tune 14. 1902.v Serial No. 111.631.(No model.)

T0 t/Z when?, it may concern:

Be it known that I, CARL HEINRICH PRTT, a citizen of the German Empire,residing at Rheydt, in the Province of Rhenish Prussia and Kingdom ofPrussia, Germany, have invented certain new and useful Improvements inApparatus for Dispersing Liquids or Making Spray; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertaius to make and use the same.

The present invention has for its object an improved apparatus by meansof which the air in rooms-say in factory-rooms, in rooms of hospitals,and others-can be saturated with liquids in a line spray like a fog orvapor and whereby the liquid may be mixed with solutions of chemicalsfor sanitary purposes or with odoriferous bodies for perfumiug the airor where pure water only may be used for technical purposes--as, forinstance, in cotton-mills. I attain this object by bringing the liquidto be dispersed in fine dust upon a disk rotating very quickly, so thatthe liquid by the action of centrifugal force will be thrown out in alldirections in a fine spray, but whereby this spray or these lineparticles of liquid will be thrown against the wings or into the cellsof a xed ring surrounding the rot-ary disk and composed of a greatnumber of vanes or wings standing out radially inwardly from a ring towhich they are fixed, and thus forming cells open on all sides except atthe outer circumference, so that a current of air driven into or throughthe cells from above carries away the vapor into the room where theapparatus is erected.

On the accompanying drawings I show the new apparatus in .Figure 1 in acentral vertical section along line I I of Fig. 2, and in Fig. 2 in ahorizontal section along line II 1I of Fig. 1.

The apparatus is composed of a basin 1, of glass or metal. Ou columns 2,fixed to the bottom of the basin 1, is held centrally to the latter aU-shaped ring or trough 3 of somewhat smaller exterior diameter than theouter edge of the basin and open in the middle, so that arelativelynarrow ring-shaped passage between the outer edges 4 and 5 ofthe basin 1 and of the trough 3, respectivelyais left free.

At the inner edge of the trough 3 are arranged a number of radial wingsG. In the center ot the basin 1 is fixed toits bottom apot 7, serving asa bearing for the rotary distributer 8. This consists of a parabolicpiece running out at its largest diameter in a horizontal disk f). Thelower parabolic circumference is tinely polished, and the diskElstandsabout iu the middle ofthe wings o' of the trough 3. The lowerpart of the paraboloid is surrounded by a similarlvshaped casing 10,fixed to the outside of the pot 7 and leaving only a relatively narrowspace between both. 'lhe upper side of the paraboloid is coupled to thespindle 12 of an electromotor 11, mounted between the columns 2, so thatwhen said motor is at workl it will take around the paraboloid at a veryhigh speed. Between the electromotoraud disk S is fixed upon the spindle12 a fan 13, having its wings so shaped that it forces the air downwardthrough the cells formed by the wings 6 of the trough 3.

It will of course be understood that the paraboloid instead of beingdriven by au electromotor may he driven by any other motive force. Thespindle 12 then would be prolongated outside of the cover 14, where itwould be provided with a pulley or other suitable means for receivingpower.

The casing 10 is made adjustablethat is to say, it can be turned aroundby a handle 15, so as to regulate the entrance of liquid into theinterior of the casing l0 by the slits 16 in the circumference of thiscasing and in the pot 7.

The inner side ot' the trough 3 has a channel 17 at its lower edge fortaking up drops of water which may gather there.

A perforated sheet-iron casing 11 may be put around the upper part ofthe apparatus,

The working of the apparatus is as follows: The basin 1 is filled withwater or other liquid, but so much only that there is left afree passagebetween the surface ot the waterand the lower edge of theY channel 17 orof the trough 3, respectively, about equal in width to the distancebetween the basin and the trough near their upper edges. The casing 10with regard to the pot 7 is so adjusted that water can enter through theslits 16 into the interior of the casing in suicient quantity. Theparaboloid 8 9 is then made to turn rap- IOC idly with the fan 13 by theelectromotor or by some other motive power. In consequence of this quickrotation the liquid rises along the peripheryof the paraboloid 8 and isthrown out at the edge of the disk 9 by the centrifugal force anddispersed in a spray against the wings 6. The stream of air blowndownward through the cells by the fan 13 supports the dispersing action,and thus it follows that the air saturated with the spray is driven outat the circumference 4 of the basin 1 in as perfect manner as can bedesired.

I am aware that various apparatus have been devised for distributingliquid in a fine spray and for saturating air with Water, and I do not,therefore,clain1, broadly, such an apparatus; but

What I do claim, and desire to secure by Letters Patent, is-

1. In an apparatus fordispersing liquids or making spray a basin lcontaining the liquid to be dispersed in combination with aparaboloid-shaped body 8 ending in a horizontal disk 9, a pan or bearing7 carrying the foot of said paraboloid, a spindle 12 at top of theparaboloid, afan 13 keyed to said spindle, an electromotor driving saidspindle and the paraboloid, columns 2 fixed to the bottom of the basin1, a U-shaped trough 3 fixed to said columns centrally over the basin 1,so as to leave au annular space between the side of the basin 1 and theoutside edge of the trough, a series of radial wings 6 forming cells andarranged exactly in the level of the disk 9 at the inner side of thetrough 3, the whole as described and illustrated and for the purpose setforth.

2. In an apparatus for dispersing liquids or making spraya basin 1containing the liquid, columns 2 fixed to the bottom of said basin, aU-shaped trough 3 fixed to said columns centrally over the basin so asto leave an annular space between the side of the basin 1 and the outeredge of the trough 3, a channel 17 at the foot of the trough 3, wings 6projecting radially inward from the inner side of the trough, incombination with a rotating paraboloid-shaped body 8 guided in a pan 7fixed to the bottom of the basin 1, a spindle 12 projecting upward fromthe top of the paraboloid 8, a fan 13 keyed to said spindle, anelectromotor coupled to the spindle and driving the same at a highspeed, a perforated casing 18 surrounding the upper part of theapparatus, a cover 14 at top of said. casing 18, an adjustable casing 10surrounding the lower part of the paraboloid and the pan 7, slits 16 insaid casing 10 and in the pan 7, a hand-lever 15 for adjusting the Widthof opening of the slits 16 and regulating the How of liquid into thespace inside of the casing 10, the whole as described and illustratedand for the purpose set forth.

In testimony whereof I have affixed my signature in presence of twoWitnesses.
